1 Claim. (Cl. 292341.18)

This invention relates to strike plates for door lock mechanisms.

It is an object of the present invention to provide a strike plate fordoor locks which is adjustable vertically with a minimum of time andeffort in the event that the door jamb should sag.

It is another object of the present invention to provide an adjustabledoor lock strike plate of the above type which may be adjusted laterallyin a horizontal position to compensate for warpage or shrinkage with aminimum of time and efiort.

Other objects of the invention are to provide an adjustable door lockstrike plate bearing the above objects in mind which is of simpleconstruction, has a minimum number of parts, is inexpensive tomanufacture and efficient in use.

For other objects and a better understanding of the invention, referencemay be had to the following detailed description taken in connectionwith the accompanying drawing, in which:

Figure 1 is a perspective view of a preferred embodiment of the presentinvention shown in operative use;

Fig. 2 is an end elevational view thereof and Fig. 3 is a top plan Viewshown alone of the inner element forming a part of the invention.

Referring now more in detail to the drawing, represents a door which ishingeably mounted within the jamb in the usual manner of suchconstructions, the jamb being indicated by the reference numeral 11.

In the practice of my invention, an adjustable door lock strike plate isprovided and includes the outer T-shaped plate 12 which is securedwithin the usual recessed portion of the jamb by means of the mountingopenings at opposite ends and the screws 13, as shown in Fig. 1.

The invention includes an inner plate 14 of rectangular shape which isprovided with the usual central rectangular opening 15 which fits withinand is in lateral alignment with the larger opening 16 of rectangularshape provided in the outer member 12. The opening 15 cooperates withthe conventional door lock member in a manner which will be apparent tothose skilled in the art.

The inner plate 14 at the upper and lower ends thereof is provided withthe stepped notches 17 which receive therethrough the screws 13 andwhich permit the vertical or lateral adjustment 'of the inner plate 14and therewith the opening 15 thereof.

The invention may be used for either metal or wood door jambs as well asfor doors having a locking device and a floor saddle and head jamb.

It should now be apparent that there has been provided an adjustabledoor lock strike plate which may be adjusted to any door with a minimumof cost in the event that the door or jamb should sag in the verticalposition simply by loosening the screws 13 and moving the inner plate 14up or down and then again tightening the screws 13. It should also beapparent that there has been provided an adjustable door lock strikeplate which will permit the adjustment of door in or out against thedoor stop in a horizontal direction due to warpage or shrinkage (in thecase of wood) or in the case of metal due to other factors by merelyloosening the screws 13 and again moving the plate 14 in a lateraldirection whereupon the screws 13 will again be tightened. The steppednotches 17will permit the adjustment against the jamb or door in orderto cope with any misadjustment of the jamb or door that may arise.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claim.

Having thus set forth and disclosed the nature of my invention, what isclaimed is:

An adjustable door lock strike plate comprising an outer platepositioned within the door jarnb recess, means for securing said outerplate to the door jamb, said outer plate having a central rectangularopening therethrough, and an inner rectangular plate disposedintermediate said outer plate and the jamb, the said inner plate havinga central rectangular opening positioned within said outer plateopening, and stepped notched means at opposite ends of said inner plateto permit the lateral or vertical adjustment of the same in the centralopening thereof upon loosening said mounting means, said stepped notchmeans comprising a plurality of aligned alternately arranged steps andrecesses on each side of the vertical lon gitudinal center plane of saidinner plate at the upper and lower extremities thereof, each stepportion at the upper and lower extremities at one side of said centerplane being in facing arrangement with a recess on the opposite side ofsaid center plane, and said means for securing said outer plate to thedoor jamb comprising screw means passing through mounting openings insaid outer plate and through said inner plate, said screw means-beingdisposed adjacent to a step on one side of said inner plate center planeat the upper extremity thereof and disposed adjacent to a step on thesame side of said inner plate center plane at the lower extremitythereof, whereby one extremity of said inner plate is prevented frombeing moved in a direction opposite to the direction of movement of theopposite extremity thereof by abutment of said steps with said screwmeans.
